Please be sure to check the profile as well. This was given to me about 30 years ago. I didn't know how to polish it, so I've never polished it. I used it for 2-3 years, about once a month. Of course, I don't know the original price, the brand, or the material. I would appreciate it if you could judge everything from the images. If you have any questions, such as wanting a close-up image of a certain part, I will answer them as best I can. Please refrain from returns due to differences from what you expected after purchase. Regarding the size: As shown in the image, the back can be adjusted, so it should increase by a few sizes when opened. For reference, it was a little loose on me, and I usually wear a size 9. Since it's been a long time, I will sell it as is without touching it. I have no idea how to handle old metal, so I don't know the material, I apologize. For your reference, the weight is 13 grams, measured at home. It may have been a cheap item originally, but considering its age, I recommend it to vintage lovers regardless of the brand. Anonymous shipping Please refrain from price reductions. There is no case, so I will wrap it in bubble wrap and ship it. It will be sent via Yu-packet mini. Skull Skeleton
